Senior Front End Application Developer
AI-Assisted Development

Todd HeckelerFront-End Developer

I build AI-assisted development workflows and infrastructure that enable platform-wide improvements. At Sherwin-Williams, I created custom GitHub Copilot Agent Skills, automated platform analysis, and developer tooling that achieved 28% faster JavaScript execution and zero production vulnerabilities across 10 micro frontends. I use AI as a force multiplier to work at the architecture level while handling implementation efficiently. Experienced in Module Federation architectures, design systems, and performance optimization.
